Question

Argon is called insert gas why?

Answer 1

❧Hi my dear friend,

They are helium, neon, argon, krypton, xenon, and radon. They were once called inert gases because they were thought to be completely inert—unable to form compounds. This is a reasonable belief because the noble gases have a complete octet, making them very stable and unlikely to gain or lose any electrons.

~Thank you☙
